Contacting Michael Bowyer?

Just out of interest, does anyone have a reliable address or contact method for Michael J.F. Bowyer, author of so-many aviation history books?

A book of his I read while at school has led to a fifteen year quest to research a certain RAF unit and I’ve come across some interesting evidence I’d like his opinion on.

I thought about asking the publishers Crécy but I’d prefer a way to write to him more directly.

Thanks for any help.
